    摘要: A method for producing an electrode material wherein particles containing Cr are miniaturized and uniformly dispersed and Cu portions, which serve as a highly conductive component, are also miniaturized and uniformly dispersed. This method for producing an electrode material involves: a mixing step (S1) for mixing a heat resistant element powder and a Cr powder; a provisional sintering step (S2) for obtaining a solid solution of the heat resistant element and Cr by provisionally sintering the mixed powder; a pulverizing step (S3) for obtaining a solid solution powder of the heat resistant element and Cr by pulverizing the solid solution of the heat resistant element and Cr; a molding step (S4) for molding the solid solution powder; a main sintering step (S5) for obtaining a sintered body (skeleton) of the heat resistant element and Cr by subjecting the thus-obtained molded body to main sintering; and a Cu infiltration step (S6) for infiltrating the sintered body of the heat resistant element and Cr with Cu.
